libvirt reloads the domain configuration from status XML (e.g. /var/run/libvirt/qemu/$domain.xml) if the status XML exists (means the domain is running) when restarting. However, it doesn't record the original domain configuration in
it's not able to restore the domain configuration to the original one when destroying and shutdown. The user will see
the not persistent attached devices still exists after restarting
Record the original domain configuration by assigning persistent domain configuration to dom->newDef if it's NULL and the domain is running.
The not persistent attached device will not exist after libvirtd is restarted, which is the correct logic.
